--- Comment #3 from Aleksandar Petrinic <petrinic at gmail dot com> ---
I investigated this bug a more further and this is only triggered when gold is
used in combination with -Wl,--as-needed. I'm on Exherbo and will attach cave
info.

Anyway, take a look:

x86_64-pc-linux-gnu-g++ -pthread -std=gnu++0x -pedantic -ggdb -O2 -pipe
-march=native -pedantic -c -o print_exports.o print_exports.cc

x86_64-pc-linux-gnu-g++ -pthread -std=gnu++0x -pedantic -ggdb -O2 -pipe
-march=native -pedantic -o print_exports print_exports.o  -Wl,--as-needed
-pthread -Wl,-fuse-ld=gold

./print_exports -->(segfault)

x86_64-pc-linux-gnu-g++ -pthread -std=gnu++0x -pedantic -ggdb -O2 -pipe
-march=native -pedantic -o print_exports print_exports.o  -Wl,--as-needed
-pthread -Wl,-fuse-ld=bfd

./print_exports --> works

x86_64-pc-linux-gnu-g++ -pthread -std=gnu++0x -pedantic -ggdb -O2 -pipe
-march=native -pedantic -o print_exports print_exports.o -pthread
-Wl,-fuse-ld=gold
(Pay attention... as-needed is missing here)

./print_exports --> works
